Project Summary

Harvey Janszen (July 11, 1946–May 10, 2021) was an accomplished amateur botanist and naturalist endeared to many in British Columbia’s natural history community. During his career, Harvey collected over 3,000 vascular plant specimens, mostly from the southern Gulf Islands of British Columbia, and curated comprehensive species checklists documenting the flora of the southern Gulf Islands, Saanich Peninsula, San Juan Islands, and various other localities throughout the Salish Sea.

History of collection activities

To chronicle this legacy, Harvey left behind field journals documenting his collection activities throughout the region, from 1973 to 2017. Many of these historical baseline records have not been digitized and so remain unavailable to the scientific community. Through the Janszen Legacy Project, we are actively curating and preserving these important records, including herbarium specimens, list records, and field notes. In the following maps, we provide a summary of the progress of this initiative to date, with reference to the journals and species lists that Harvey left us with.

Flora of Saturna ca. 1973–1981

The journal includes collections numbering from 1,930 to 2,629.

Journal ca. 1996-2000

Journal documenting botanical surveys of: Metchosin (1996), Saturna Island (1996, 1998, 1999, 2000), Saltspring Island (1996), Sidney Island (2000), Texada Island (1997, 1999), Tumbo Island (1998), and Valdes Island (1998). The journal includes collection records numbering from 2,630 to 2,920, including detailed population assessments and georeferenced localities for Woodwardia and various Ophioglossaceae, as well as field notes and species lists.

Field notes ca. 1999–2003

Field notes documenting floristic inventories of: the Cowichan River (2003), Galiano Island (2002-2003), Hornby Island (2002-2003), Mount Tzouhalem (2003), Saturna Island (1999–2003), Sidney Island (2000–2003); and surveys targetting Crassula connata on Saltspring Island (2000–2003), Tree Island (2003), and Valdes Island (2003). Collections numbering from 2,921–2,961.

Field notes ca. 2003–2017

Field notes documenting floristic inventories of Galiano Island (2004), Lake Helen Mackenzie (2010), Saturna Island (2003-2010, 2013), Strathcona Provincial Park (2007), Tumbo Island (2007), and Valdes Island (2017)—including records of rare vascular plant species such as Meconella oregana, Ranunculus californicus, and Sanicula bipinnatifida. Collections numbering from 2,962–2,971.

Curation of regional species lists

Before Harvey passed, he reached out to several botanists to invite their review of the comprehensive species lists he had dedicated his life to compiling for the region. Today, we are honouring his final request and collectively reviewing the flora of the southern Gulf Islands, Saanich Peninsula, San Juan Islands, and surrounding islets. Curation of the flora of the San Juan Islands is being led by Peter Dunwiddie and Adam Martin. Annotated checklists documenting the flora of the Saanich Peninsula and southern Gulf Islands will be published as an open access resource under Harvey’s name.

Proposed project outcomes

Harvey’s dataset establishes a critical baseline record of the vascular plant diversity of the southern Gulf Islands, Saanich Peninsula, and San Juan Islands. This baseline is a vital resource for conservation, and for improving our general understanding of the floristics of the region and our future understanding of ecological change.
